.TH "DNF4-VERSIONLOCK" "8" "Aug 22, 2024" "4.9.0" "dnf-plugins-core"
.SH NAME
dnf4-versionlock \- DNF versionlock Plugin
.SH DESCRIPTION
.sp
\fIversionlock\fP is a plugin that takes a set of names and versions for packages and
excludes all other versions of those packages. This allows you to protect
packages from being updated by newer versions. Alternately, it accepts a specific
package version to exclude from updates, e.g. for when it\(aqs necessary to skip a
specific release of a package that has known issues.
.sp
The plugin provides a command \fIversionlock\fP which allows you to view and edit the
list of locked packages easily.
.sp
The plugin will walk each line of the versionlock file, and parse out the name and
version of the package. It will then exclude any package by that name that
doesn\(aqt match one of the versions listed within the file. This is basically
the same as using \fIdnf \-\-exclude\fP for the package name itself (as you cannot exclude
installed packages), but dnf will still see the versions you have
installed/versionlocked as available so that \fIdnf reinstall\fP will still
work, etc.
.sp
It can also work in the opposite way, like a fast exclude, by prefixing a \(aq!\(aq
character to the version recorded in the lock list file. This specifically
excludes a package that matches the version exactly.
.sp
Note the versionlock plugin does not apply any excludes in non\-transactional
operations like \fIrepoquery\fP, \fIlist\fP, \fIinfo\fP, etc.
.SH SYNOPSIS
.sp
\fBdnf versionlock [options] [add|exclude|list|delete|clear] [<package\-name\-spec>]\fP
.SH ARGUMENTS
.INDENT 0.0
.TP
.B \fB<package\-name\-spec>\fP
Package spec to lock or exclude.
.UNINDENT
.SH SUBCOMMANDS
.INDENT 0.0
.TP
.B \fBdnf versionlock add <package\-name\-spec>\fP
Add a versionlock for all available packages matching the spec. It means that only versions of
packages represented by \fB<package\-name\-spec>\fP will be available for transaction operations.
Each \fB<package\-name\-spec>\fP is converted to concrete NEVRAs which are used for locking. The NEVRAs to lock to are first searched among installed packages and then (if none is found) in all currently available packages.
.sp
Examples:
.INDENT 7.0
.INDENT 3.5
.sp
.EX
Locking a package to the version installed:

    $ dnf repoquery \-\-installed bash
    bash\-0:5.0.7\-1.fc30.x86_64

    $ dnf repoquery bash
    bash\-0:5.0.2\-1.fc30.i686
    bash\-0:5.0.2\-1.fc30.x86_64
    bash\-0:5.0.7\-1.fc30.i686
    bash\-0:5.0.7\-1.fc30.x86_64

    $ dnf versionlock add bash
    Adding versionlock on: bash\-0:5.0.7\-1.fc30.*

Locking not installed package to any of available versions:

    $ dnf repoquery \-\-installed mutt

    $ dnf repoquery mutt
    mutt\-5:1.11.4\-1.fc30.x86_64
    mutt\-5:1.12.1\-3.fc30.x86_64

    $ dnf versionlock add mutt
    Adding versionlock on: mutt\-5:1.11.4\-1.fc30.*
    Adding versionlock on: mutt\-5:1.12.1\-3.fc30.*

.sp
\fBNOTE:\fP
.INDENT 7.0
.INDENT 3.5
Be careful when adding specific versions
.sp
If you add a package specifying a version with \fBdnf versionlock mutt\-5:1.11.4\-1.fc30.x86_64\fP then, if you run \fBdnf versionlock add mutt\fP
versionlock will not add \fBmutt\-5:1.12.1\-3.fc30.x86_64\fP\&.
.UNINDENT
.UNINDENT
.TP
.B \fBdnf versionlock exclude <package\-name\-spec>\fP
Add an exclude (within  versionlock) for the available packages matching the spec. It means that
packages represented by \fB<package\-name\-spec>\fP will be excluded from transaction operations.
.TP
.B \fBdnf versionlock list\fP or \fBdnf versionlock\fP
List the current versionlock entries.
.TP
.B \fBdnf versionlock delete <package\-name\-spec>\fP
Remove any matching versionlock entries.
.TP
.B \fBdnf versionlock clear\fP
Remove all versionlock entries.
.UNINDENT
.SH OPTIONS
.sp
All general DNF options are accepted, see \fIOptions\fP in \fBdnf(8)\fP for details.
.INDENT 0.0
.TP
.B \fB\-\-raw\fP
Do not resolve \fB<package\-name\-spec>\fP to NEVRAs to find specific version to lock to. Instead \fB<package\-name\-spec>\fP are used as they are. This enables locking to not yet available versions of the package.
For example you may want to keep the \fIbash\fP package on major version 5 and consume any future updates as far as they keep the major version:
.INDENT 7.0
.INDENT 3.5
.sp
.EX
$ dnf versionlock add \-\-raw \(aqbash\-5.*\(aq
Adding versionlock on: bash\-5.*
.EE
.UNINDENT

.SH CONFIGURATION
.sp
\fB/etc/dnf/plugins/versionlock.conf\fP
.sp
The minimal content of conf file should contain \fBmain\fP sections with \fBenabled\fP and
\fBlocklist\fP parameters.
.INDENT 0.0
.TP
.B \fBlocklist\fP
This option is a string that points to the file which has the versionlock
information in it. Note that the file has to exist (or the versionlock plugin
will make dnf exit). However, it can be empty.
.sp
The file takes entries in the format of \fB<package\-name\-spec>\fP (optionally prefixed with \(aq!\(aq for
excludes).
See \fISpecifying packages\fP in \fBdnf(8)\fP for details.
.UNINDENT
.SH NOTES
.sp
A specified package does not have to exist within the available cache of repository data
to be considered valid for locking or exclusion. This is by design, to accommodate use
cases such as a presently disabled repository. However, a package must exist in the
repository cache when the \fBadd\fP or \fBexclude\fP subcommands are invoked for it.
